The Joyner–Boore Attenuation Data
乔伊纳 - Boore衰减数据
译者:生物统计家园网 机器人LoveR
描述----------Description----------
This data gives peak accelerations measured at various observation stations for 23 earthquakes in California. The data have been used by various workers to estimate the attenuating affect of distance on ground acceleration.
这个数据给出了在不同的观测站的测量23日在加利福尼亚州的地震峰值加速度。已使用的数据由不同的工人估计衰减距离地面加速度的影响。
